The greenhouse is ALSO ABOVE the fenders, as it is on practically everything. Are we still having trouble with the concept of frontal area?
Imagine a cone, pointy end leading into the flow. The area at the front is almost nothing; the area at the very very rear is the entirety of the "frontal area" even though it's at the rear. Frontal area is the size of the hole punched through the air; forget about if that occurs at the front or not. More intuitive terminology for it could be "maximum cross sectional area with consideration for variations from front to rear" (because the max cross-sectional slice of the typical road vehicle body wouldn't have the wheels and tires represented) or "The Wile E. Coyote silhouette through the fake paper road and landscape" but it is what it is.
